Just a suggestion, but there should be a "how high can you go %" (bad name ik)

For instance: https://www.speedrun.com/HalfSwordPlaytest

This game is basically just you fighting an AI, and you so the counter of how far you can go is counted in MS, so for instance, in R.E.P.O's case, if a player makes it to level 5, the finalized time of the run on speedrun.com would be:

0m-0s-005ms

Now, I don't really know that this would work, as I'm pretty sure there is a limit to how far humanly you can go, or maybe I don't really know anything and the game ends at level 10? Not really sure about this, if someone could elaborate that would be great. Thanks! :)
